Question about Projection Televisions
The most common failure that causes your symptoms is a failure of the SUS boards, or sustain boards which drive the panel. There are two sets of sustain boards, X and Y (or Y and Z for some manufacturers), one set each to drive the horizontal and vertical signals for the panel. The bad news? It isn't something a consumer can diagnose or replace, for the most part. There are DANGEROUS voltages inside your set that can easily kill or cause serious injury. After replacing sustain boards there are certain adjustments required that ned to be performed by a qualified tech. So, you'll need a tecnician to look at it for you. Sorry!
